To all rv/2.0m it may concern Be it known that I, Manner: O. KASSON,

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Internal-Combustion Motors; and I do hereby declare the fol ing the invention: Figure l is an end elevation of a motor embodying the invention. Fig. -2- is a central vertical longi: tudinal section of the same on the line 2--2-" of Fig. '1-. Fig. "3 is a detail vertical transverse section of the same on the line 33 of Fig. 2-. Figs. -4- and 5' are respectively diagrammatic views illustrating different electric clrcuitsyand the means and manner of opening and closing the same whereby the explosion of gases in the cylinders is effected.

Many attempts have been made to produce an efficient rotary motor of the internal combustion type but, so far as I am 1nformed, these have proved to be commercially impractical for the reason "that the charges of combustible fluid to be exploded to provide the motive force were not compressed to a sufiicientextent prior to'ignition to-yield the degree of expansive effic'iency upon which motor efliciency is dependent. Such motors have, so far as I am informed, been designed to ignite the charge While disposed between the relatively movable parts to be actuated by expansion thereof, and, because of the lack of compression above referred to, and also to other difficulties presented by this class of motors, the increase'in pressure due to expansion by ignition has been too small to yield commercial efficiency. i

My invention is intended to overcome this difliculty by utilizing the gases after their ignition and exhaust from one or more com- Specificatian of Letters Patent.

.utilized. The

parts. hereinafter fully Patented Aug. 31, 1915 bus'tion chambers to develop powene. e. pr0- pulsive mechanical movement. In other propose to employ the products of combustion under pressure in a manner similar to that in which steam under pressure is problem presented appears to be most easily solved in the rotary type of motor, the mostsuccessful example of which is seen in the turbine. illustrated the invention as embodied in. this type of motor or enginebut the principle or law of nature upon which it is based may I be capable of application to other forms or types of motors.

The embodiment of the invention illustrated comprises two main parts, *viz: that part which generates and directs the motive forcaqsmd that part upon which it is directed and by means of which it is transformed. 'nto'propulsive mechanical motion. The latt r is bestexem'plified by the turbine which" is. diagrammatically illustrated and may-hevariously constructed to best utilize the motive force by persons skilled in tur bineengineering. Means must be provided for utilizing a part of the motive force for actuating its genera-tor. In that part of the motor which generates the motive force I utilize centrifugal force in maintaining the combustible charge under compression at the time of ignition and for discharging the products of combustion under pressure into the turbine end of the motor. Hence, a part must be absorbedof the power generated by the generating medium for the performance of its function as in all of the approved types of internal combustion motors.

The general object of the invention'will be readily understood from the foregoing.

This may be more specifically stated as follows:

One object of my invention is to provide arotary motor of the internal combustion type in which the gases to be exploded are compressed prior to ignition whereby an eX- I have, therefore,

)losive force of considerable ma nitude is l obtained. p

A further object of the invention is to pro vide means whereby the discharge of each ignited charge from an explosive or combustion chamber into the means adapted to be actuated thereby is followed by a discharge of cool compressed air into such means for the purpose of cooling and also actuating the same.

Another object of the invention is to provide means whereby the relative rotation of 1 .parts of the means actuated-by the discharge of burnt gase's provides a force which is utilized for maintaining a relatively constant pressure on the products of combustion during discharge thereof for actuating the said means.

Other objects of the invention will appear from the following description.

The motor as illustrated comprises the shaft 1 suitably journaled in bearings 2 and 3 disposed in standards 4: of any suitable construction and which carries a plurality of disks 5 equipped with annular flanges 6 from which blades 7 angularly disposed relatively to the axis of the shaft 1 project radially and which are connected together at their outer ends by means of a rim 7 concentric with the flanges 6. The said disks 5 and the parts carried thereby alternate with similar disks 8 and blades 9, the latter angularly disposed relatively to the axis of the shaft 1 in a direction opposite to the planes of the blades 7 whereby zig zag passages are provided-between contiguous alternate pairs of said blades 7 and 9. The said blades 9 are integral at their outer ends with the casing rings 10. Each of the latter is provided with an annular recess 11 contiguous toone end thereof in which a rim 7 of the blades or vanes of a disk 5 is rotatable. All of the casing rings 10 are also provided with outwardly extending annular flanges 12 which are adapted to be bolted or otherwise secured together to couple all of said rings 10 into a housing or casing. The latter is provided With an end wall 13 having an exhaust chamber 14 which connects with the exhaust port 15 for gases. Said casing is similarly provided with an end wall 16 which carries the combustion cylinders 17 and a rotary compressor casing 25, which will be hereinafter more particularlv described.

The details of construction of the members 5 and 8 respectively, and the relative angular disposition of their blades 6 and 9 does not constitute, in the specific form herein shown, a part of the invention as said parts may be changed and varied in accordance with turbine engineering practice for the attainment of the best results without departing from the invention. The accompanying drawings are to be considered as showing merely diagrammatically a structure suitable for my purposes Without particular regard to specific details of construction.

Disposed upon the end wall 13 of the turbine casing is a bevel gear 18 and carried rigid with the shaft 1 is a similar bevel gear 19, the face of which is opposed to the gear 18. Bevel pinions 20 carried by shafts 21.

suitably ournaled in bearings carried by one of the standards 4 mesh with both said gears 18 and 19 and cause the casing of the turbine to rotate in a direction opposite to the direction of rotation of the shaft 1 and parts carried thereby, and in the instance illustrated, at the same speed. The relative speeds of rotation may be varied at will without departing from the invention. The said shaft 1 is hollow contiguous to its other end and is connected at said end with a suitable supply of carbureted air, such for example as the carbureter 22 shown diagrammatically in Fig. 2. Said shaft is provided with ports 23 through which the carbureted air or other combustibleilmixture is-admitted to the central chamber 2.1 of the compressor 25. The latter, as herein shown, is of the rotary type, this being deemed a suitable type for use in this connection, though any other type may be substituted without departing fromthe invention.

The compressor herein shown comprises a cylindrical casing 26 and an inner concentric casing member 27, the latter being disposed to rotate with the shaft 1 and the former to rotate with the end wall 16 of the casing.

Disposed between said members 26 and 27 and rigid with the end wall 16 of the turbine casing is a cylindrical member 28. The said member 28 is disposed eccentrically relatively to the members 26 and 27 and is provided with a port 29 establishing communication between the respective chambers on either side thereof; said port 29 being located at the point in the member 28 which is disposed radially nearest to the axis of the shaft 1.

The member 27 is provided with a, plurality of ports 30 eachcontrolled by springactuated check valve 31 and throughwhich the explosive gaseous mixture is adapted to pass from the inner chamber 2+1 of the compressor to the chamber 32 between the members 27 and The member 27 carries a plurality of blades or piston members which, as herein diagrammatically shown, are each pivotally connected with said member 27 and at their outer ends are adapted to contact with the inner wall of the member 28, said blades being of a width equal to the width of the chamber 32 and cmstructed similarly to similar or equivalent piston members of rotary compressors to provide substantially fluid-tight joints between the several edges thereof and the parts with which they contact. The said blades 33 are normally held in position so that their outer edges contact with the inner wall of the member 28 by means of springs 34 which supplement the centrifugal force which, during rotation of the member 27, would cause said blades to remain normally in the positions shown in Fig. '3-. Each of said blades is pivotally mes es 29-into the chamber 35 between the member 2 8 and the member 26. ()bviously, during the relative rotation of the members 27 and 28 the gases contained in the several chambers between contiguous blades 33 will be compressed and will attain the greatest degree of compression at the time that eachblade approaches the exhaust port 29 through which the compressed gases are then. exhausted. The illustration of the compressor is purely diagrammatic and exemplary. I

- The several cylinders 17 are also rigidly mountedon the said end wall l6'ot' the turbine casing. Each of the same is provided with a main chamber 36 and an auxiliary chamber 37 of smaller diameter. end portion of the chamber" 36 of the cylinder communicates by means of a pipe 38 connecting with a passage 39 in the cylinder head and through a port 40 controlled by the check valve 41 with the chamber from which it receives a supply of combustible gas under pressure. In each of said cylinders there is provided a reciprocating piston d2 of the trunk type which is provided.

with an extension portion 43:01? smaller diameter fitting and reciprocally movable in the portion 37 of said cylinder, said piston being hollow for reasons which will herelnafter appear. Each of said pistons l2 is adapted to be normally held at the outer limit of its movement by centrifugal force imparted thereto by the rotation. of the turbine casing and is adapted to be moved toward the inner limit of its movement against the action of said centrifugal force by the action of the compressed gases entering the same through said port 46. The degree of compression of the gases to be exploded in the several'cylinders 17 will depend primarily upon the pressure in the chamber 35 and upon the weight of each of said pis tons l2, its distance from the axisot rotation, and the speed of rotation. The pres sure in said chamber 35 must be suiiicient primarily to overcome the springs controlling the valves 41 and the centrifugal force maintaining the pistons at the outer limits of their movement.

The pistons of the cylinders are free to rotate within the latter and, therefore, in order to provide means for electrically igniting the charge as the latter is introduced in each cylinder the port -10 is disposed'to one side of the center of the cylinder head and a sparking device or spark plug is introduced into the center of said head. This consists'of a plug of fiber or in, pressure The upper which as said piston approaches the outer limit of its movement passes between the terminals 4A- and thereby closes the electric circuit between the same. As the explosive charge under pressure forces the piston inwardly the said pin {to will be withdrawn from engagement with said terminals 44 thus breaking the circuit and causing a spark to jump at this point thereby igniting charge and exploding it. The increase due to the explosion of the charge will immediately close the check valve 41 and force the piston toward the lower limit oi its movement. Said piston. when at or near the outer limit of its m vement covers the exhaust port 46 through which the exploded charge is projected into the turbine portion of the motor. This port is relatively small so that the pressure in the upper portion of the cylinder 17 cannot instantly fall to zero but will exceed for a time at least, the pressure due to the centrifugal force exerted upon the piston to force the latter farther toward the lower limit of its movement.

The lower end portion 37 of the cylinder is'provided contiguous vto'i'ts outer end with a plurality of ports i? through which air may enter said cylinder. These ports are adapted to be closed as the piston is forced downwardly by admission of the charge under pressui'e and its explosion thereby trapping the air contained in said portion 37. The lower end of the piston is-equipped with a head provided with a passage 48 which is controlled by the check valve 49 and through which and the passage 50 the air compressed inthe portion 37 of the cylinder enters the inner chamber 51 of said sealed until said piston again moves toward the outer limit of its movement and said groove 53 communicates with the exhaust port 46 whereupon sale air under pressure thus trapped within the piston is exhausted into the turbine end of the motor where it not only exerts its force toward propulsion but by reason of its being cool serves to reduos thetemperature within the said turbine.

& l

The portion 54 of the cylinder disposed between the wall 55 at the lower end of the portion 36 and the upper end of the portion 37 is provided with an. inlet and exhaust port 56 through which airis exhausted and received as said piston reciprocates. The lower end portion 37 of said. piston is also provided with a check valve control inlet port- 57 through which air in enter as said piston moves toward the outer limit of its movement after receiving a charge of compressed air from said portion 37 of said cylinder. The motor may be operated in two different 'ways so far as the explosion of charges in the various cylinders is concerned as will be readily understood when it is considered that there is no valve mechanism controlled by the piston movements and in turn controlling the admission and exhaust of charges. The charge is always seeking to enter the cylinder and will do so as soon a as the pressure on the inner face of the check valve 41 recedes to a point below that which the fcharge pressure can overcome. This would obviously follow each discharge from the cylinder so that the frequency of explosions alone controls the admission of fresh charges. Obviously this may take place a few or a'great'number of times per revolution in each cylinder depending entirely upon the s stem of ignition used. The ignition may be accomplished in a number of dilferent ways. The preferable way is to provide a separate source of current for each cylinder so that the charges may be received and ignited therein just as frequently as this i can be accomplished. All other systems of ignition must probably be of such a nature as to time the explosions so that each charge is exploded in each cylinder as the latter passes one or more points in its rotation about the turbine axis. 7

-I have diagrammatically illustrated two systems of ignition adapted to the purpose which I will now proceed to describe.

In Fig. 4 I have diagrammatically illustrated a system of ignition which is unti'med. This comprises a pair of terminals 4:1 in each cylinder each connected with one end of the secondary winding of an induction coil 58 mounted to rotate with the cylinders 7. A pin 45 (shown in Fig. mounted in the center of the piston contacts with both terminals and maintains the secondary circuit normally closed. As the piston charge, the pin 45 is withdrawn and opens the circuit whereupon sparks will jump between said terminals liand ignite such charge.

armature) is grounded at one end 59 and the other end connects with brush 60 rotatis forced inwardly by an entering- The primary winding of the coil 58 (equipped with the usual make and break ing with cylinders and having contact with a ring 61 on a disk 62 rigid with the bearing 3, said ring being connected with one pole of a source ofcurrent 63, the other pole of the latter being grounded.

In Fig. 5 I have illustrated a timed ignition in which the pin 45 is omitted, an

of which are electrically connected with each other and with one pole of a source of current 68, the other pole of which is grounded as is also the other end of the primary winding of the induction coil 69. Each time that the brush 65 passes over a contact piece 67 the primary coil circuit will be closed through the make and break thereby energizing the secondary coiland producing a jump spark to ignite the charge in the cylinder. One ring 66 and coil 69 is provided for each cylinder, the number of explosions and time of the latter in the cylinders being determined by the number and relative location of the contact pieces 67 in the several rings. The timed ignition is not deemed to be quite as advantageous as the untimed for the reason that the cylinders may receive too small a charge between intervals of ignition, or on the other hand,

they may receive too great a charge, that is in the lower end portions of the cylinders by compressing the air contained therein during the inward stroke of the piston. In this way an equalization of pressures within the cylinder and in the feed for the cylinder may be provided at a oint in the stroke of the piston outwardly o the exhaust port. With such an arrangement the timed ignition may present advantages .over the untimed but any suitable mode ofignition may be used without departing from the invention.

It will be apparent that the 'energy generated by. ignition of the gases is most efliciently directed into actuating relation to the relatively rotating parts of the motor must be suflicient at all times to overcome that force. Thus a charge will enter a cylin-.

by introducing the products of combustion under pressure into the same. This, however, heats the respective parts so that in some instances it might be advisable to direct this energy so that it will be indirectly exerted upon said relatively movable parts.

This is partly exemplified in the drawings by using a part of said energy to compress air which is then introduced into actuating relation to said parts. "While, as shown, the compressed air charges absorb only a part of the thermal energy the structure might be furthecmodified to utilize a larger part or substantially allof the energy in this way.

The mode of utilization of the power generated, that is, by directly exhaustlngthe products of combustion under pressure into the turbine end of the motor is believed to i be the most economical and preferable and subject to modifications indicated, is the only mode of utilization contemplated.

The operation of the motor or particularly the pistons in the cylinders is as follows:' The centrifugal force exerted on the pisto "s will, of corpse, vary as the speedof rotation of the cylinders varies. Hence, the pressure of the gas deliveredby the pump der and force the piston inwardly and in so doing the pin 4:3 will be withdrawn from engagement between the terminals -14 thereby causing an ignition spark to pass between said terminals as previously described. The charge. is now ignited and. in expanding forces tlie piston farther inwardly so that it will uncover the exhaust port 46 whereupon the charge will pass into the turbine chamber into which it will be delivered under the constant pressure of the centrifugal force exerted by the piston, the inward motion of which. will be arrested by the decrease in pressure due to the opening of the exhaust.

The inlet port 40 is so proportioned to the cylinder as to feed ratherslowly into the same while the exhaust rapidly and permits adrop in pressure to a very low point the moment the piston uncovers said port. Accordingly a fresh in coming charge couldnot provide sufiicient resistance in time to prevent the:return of the piston to its normal position.
